You can contact the IRS charities division to get an official answer to your question on this. There is a link to their site at the bottom of the Start Your Own Team page on

It is my understanding that the easiest way for a team to handle it is for the funds to be distributed evenly for the benefit of everyone. Otherwise, there is a lot of paperwork (if they are distributed unevenly). They can be used for anything that benefits the team that you mentioned: hotel, fuel, tournament fees, etc. Anything associated with the extraordinary expense of the World Series. Not sure about the meals--you better check with the IRS on that, but probably since you are travelling.
If you are a 501(c)(3), in your determination letter there should be a bunch of information about the kinds of things you can spend money on.
But I'm not a tax attorney, and this answer should be taken as amatuer advice, so for the best answer, contact the IRS.
